Select a less powerful Pond Pump for gentle waterfalls and for aggressive waterfalls use a more powerful pond pump. For example: if the Waterfall is 18 inches wide, an 1800 gallon per hour pump is suited nicely. For a gentler Waterfall, use a 900-1800 gallon per hour Pump and for a more aggressive flow use a 2400-3600 gph Pump.
What size pump do I need for a waterfall?
The width of the waterfall, the length of the water drop, the thickness of the curtain of water and the length of the tubing between the pump and the waterfall all affect necessary pump size. Pump flow is measured in gallons per minute or gallons per hour. For a medium flow, you need a pump that moves about 1,500 gph per foot of waterfall width.
What size pond pump do I need for a 500 gallon?
The length, width and depth should be represented in feet. It is recommended that pond water is circulated at least once per hour. For example, if you have a 500-gallon pond, you need a pump that runs 500 GPH at the height of the discharge. This is true if it also has a skimmer or waterfall.
How much tubing do I need for a pond waterfall?
You have a long stream connecting your waterfall to your pond, so you need 50’ of tubing. The pump comes standard with a 1 ½” tubing adapter, but is that really the best tubing to choose?
How do I choose a pump for my pond?
A Pump for circulating the Pond Water Only and/or Run a Pond Filter System: If the pump will be chosen to circulate pond water only, then choose a pump that circulates the pond volume at least once per hour. Calculate pond volume using the following equation: length x width x depth x 7.5 = gallons.
What is the difference between a pond pump and a waterfall pump?
Direct Drive Pond Pumps are stronger pumps usually referred to as a Waterfall Pump and best used for taller waterfalls and higher head lift situations. Direct Drive pumps usually take a little more energy since they are more powerful and since they have more parts that can wear down usually have a shorter warranty.
How do I know what size pump I need for my pond?
A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. For example, a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond.
What size pump do I need for a 6 foot waterfall?
If your waterfall is 6 feet tall from the pond surface to the top and is connected with 20 feet of hose, your pump will need to provide that 3,000 GPH at 8 feet of head height (6 + 20/10 = 8 feet).

Waterfalls. Choose a waterfall pump to match the height and width of your waterfall. The rule of thumb is for every 1 in. of spillway width, you need 100 gallons per hour flow to achieve a “sheet” look.
How big of a pump do I need for my waterfall?
For waterfalls and streams, your pump should pump at least 100 gallons per hour for every inch wide the waterfall is. For more noise and "white-water" from your falls, increase the flow rate to 200 gallons per hour per inch of waterfall width.
How do I calculate what size pump I need?
Use the pump flowrate calculation: Divide the container volume by the length of time it took to fill up to get the flow rate. 5 gallons / 1 minute = 5 gallons per minute. 5 gallons /30 seconds (0.5 minutes) = 10 gallons per minute.
Can a pond pump be too big?
A pond pump can be too big for the size of pond, causing excess water loss, increased energy usage, an uncomfortable noise level, and an unsuitable environment for plants or fish. Careful calculation of your pump needs before purchase will help to avoid future difficulties.
How much water can a 4 pump move?
A 4-inch ram pump can deliver the same amount of water to a storage tank that is 245 feet higher than the pump using the same length of 4-inch diameter steel drive line. The stream flow required for this is at least 102 gallons per minute (0.23 cfs).

Choose a pump that is at least one and one-half times the head height for optimal performance. For example, if your fountain is 30 inches tall, find a pump with a maximum lift of 45 inches or more.
How do you set up a pond waterfall pump?
Assemble the pump according to the manufacturers instructions. Place the submersible pump on the bottom of the pond with the outlet tube facing the direction of the waterfall. Lay out the outlet tube from the pump to the waterfall box or streambed where the water will enter to flow over the falls.
What kind of pump do I need for a small pond?
Minimum Pump Size Water needs to circulate through the filter at least once every 2 hours. This means that if you have a 1,000-gallon pond, you need a pump that can produce at least 500 gallons per hour or GPH. If you have fish, then it is best to double the pump's capacity to ensure that your water stays clean.
How do I choose a pump size?
Flow rate: Calculate your desired flow rate by multiplying the total volume by the time in which you want to move the liquid. For example, for a 500-gallon pond that needs full circulation once an hour, you would want to select a pump with a minimum rated flow rate of 500 GPH (gallon per hour).
Can a pond pump be too powerful?

What size air pump do I need for a 2000 gallon pond?
For water gardens (ponds with plants and goldfish) you want to circulate at least half of your total volume every hour. This means for a 2000 gallon pond you should be pumping AT LEAST 1000 Gallons Per Hour (GPH).
How many gallons per hour for waterfall pump?
Now, for every inch wide your waterfall weir is, you will calculate using 100 - 150 gallons per hour for your waterfall pump size. If you want a nice, steady flow you may use around 125 GPH or so. If you want a 'Niagara Falls' look, you may use around 150 - 200 GPH. Multiply every inch by what type of look you want.
How much lift do you need to push water from a waterfall pump?
We also have to add one foot of lift for every 10 FEET in horizontal length the waterfall pump has to push water. In our example, let's say that we need to push the water 30 feet from the pump to the top of the waterfall. We divide the 30 feet by 10 feet and we get 3 feet of lift.
Why are waterfall pumps not returnable?
Another bad thing is the fact that the pumps aren't returnable because you would have put it in potentially scummy water and no one wants to buy your returned waterfall pump. So, it's important that you figure this out correctly.
What happens if a waterfall pump is too big?
If the waterfall pump is too large, you could have too much pressure for the size of waterfall unit you have and the water will flow over the sides instead of off the front of the waterfall unit and be a huge mess. As always, if you need any help determining what size of waterfall pump you need, we're happy to help. ~~~~~.
How wide is a waterfall weir?
First, you will need to determine how wide your waterfall weir is. (A weir is the area where the water is actually falling down.)If your waterfall weir is 36 inches across, you will use 36 inches for part of this equation.
What is waterfall lift?
If you're baffled about waterfall lifts, think of it as an amount of pressure needed to go against friction and gravity.These are referred to as our horizontal and vertical lifts.
How to size a waterfall pump?
Sizing a pump for a waterfall involves determining the width the waterfall is, how high up from the pond surface the waterfall starts, and how many feet of tubing will be between the waterfall and pond pump.
How many gallon per hour pump for waterfall?
For a gentler Waterfall, use a 900-1800 gallon per hour Pump and for a more aggressive flow use a 2400-3600 gph Pump. These numbers can be adjusted for any waterfall size.
How often should a pond pump be used?
Years ago the prescribed flow rate of a chosen Pond Pump was to be able to circulate the pond at least once every two hours. This was to save on energy consumption and to keep the cost of the pond down. Now, things are more energy efficient, pumps are less expensive, and, circulating the water once an hour (Koi Ponds need to turn over the water once per hour or more often). seems to produce cleaner ponds. This means, for example, that a Pond that holds 500 gallons should be powered at a minimum by a 250-gph Pond Pump. If a Waterfall or pond filter is to be powered with the Pump, then the height and width of the Waterfall and/or the flow rate of the Pond Filter have to be taken into consideration. This can substantially bump the recommended pump size up.
How many gallons per hour should a waterfall pump move?
A good rule of thumb is to choose a Waterfall Pump that moves 100 gallons per hour for every inch of Waterfall width. Select a less powerful Pond Pump for gentle waterfalls and for aggressive waterfalls use a more powerful pond pump. For example: if the Waterfall is 18 inches wide, an 1800 gallon per hour pump is suited nicely.
What is an external pond pump?
External, or in-line, pond pump s can be used with pond skimmer filters to draw water from the pond and plumbed to most waterfall spillways or waterfall filters. Higher grade external pumps are very quiet, use very little energy, and last for many years.
Why do ponds need a pressurized filter?
Many ponds use pressurized filters because they are easy to use and easy to maintain. They are limited by the pump size, therefore, limiting the waterfall flow. This is why many ponds with pressurized pond filters have two pond pumps. Clog resistant pond pumps and magnetic drive pond pumps are best suited for this application.
Why do pond pumps run 24/7?
Pond Pumps are the heart of the Pond, the main Pond Pump must run 24/7 to keep the Pond Water healthy and oxygenated and should consequently be chosen with care . Pond Pumps, Fountain Pumps, and Waterfall Pumps have to be engineered for continuous duty (as opposed to a Sump Pump, for example, which only runs intermittently).
How to determine the size of a waterfall pump?
To determine the size pump you will need for your waterfall, you will need to know the waterfall flow rate, the length of tubing, the height of the waterfall, and the number of elbow & T fittings used. EXAMPLE: Your waterfall is 24” wide and requires 3,600 gph and is 4’ above ground level and has 10’ of tubing and 2 elbow fittings.
How many gph does a waterfall need?
EXAMPLE: Your waterfall is 24” wide and requires 3,600 gph and is 4’ above ground level and has 10’ of tubing and 2 elbow fittings.
What is waterfall flow rate?
The waterfall flow rate is how much water is flowing over a waterfall or stream to achieve the desired effect. The more water that flows over the waterfall the louder the sound of running water will be. Here are some guidelines to help you determine the waterfall flow rate based on the amount of flow you desire.
How to determine the size of a pond pump?
To calculate the volume of water in gallons, simply multiply the length x width x average depth x 7.5.
Why is it important to use the correct size of tubing for pond pumps?
It is also important to use the correct tubing size because it has a direct effect on the pond pump ’s maximum lift capability. If you use smaller tubing than specified you will limit the pump’s maximum lift and the amount of water circulated.
How big is a submersible pump?
They are placed directly into your pond or in a skimmer box or pond vault. Submersible pumps range in size from 50 to 5,000 gallons per hour. They are easy to install and are sometime a more economical solution for smaller ponds (up to 1000 gallons of water).They are also quiet and can also be used to drain your pond. If you have fish or other aquatic life in your pond, you may want to consider a model that does not use oil because there is a danger of the pump seal breaking and oil coolant leaking into the water.
What is a centrifugal pond pump?
Centrifugal Pond Pumps. External or centrifugal pond pumps are a reliable, energy-efficient option. They are installed in a dry location near your pond. External pond water pumps are suitable for larger ponds (over 1000 gallons). Compared to a submersible pump, they are typically louder and more complicated to install, ...
Why is it important to have a pump in a pond?
Choosing a pump for your pond or fountain is an important step to ensure you maintain proper water movement. Failure to keep the water properly circulated can result in stagnation, algae buildup and mosquitoes. If you have fish, plants or other aquatic life in your pond, it is essential that you keep the water healthy by evenly distributing ...
How to calculate lift of fountain?
To calculate the lift, you need to measure how far the water in your fountain has to travel from the pump’s location in your fountain to the top of the fountain where the water comes out. Then you need to select a pump that lifts higher than that measurement. For example, if that distance is 24”, than you will need a fountain pump ...
How many gallons of water can a pond drain?
They are easy to install and are sometime a more economical solution for smaller ponds (up to 1000 gallons of water).They are also quiet and can also be used to drain your pond.
How much water does a waterfall pump move?
Pump flow is measured in gallons per minute or gallons per hour. For a medium flow, you need a pump that moves about 1,500 gph per foot of waterfall width.
How to measure waterfall height?
This is called the head. The head is the amount of mechanical or gravitational resistance the pump will have to overcome. If you have 90- degree angles in your tubing, add 1 foot of head for every one to two turns .
How to determine how much water to pump in a weir?
Multiply the length of the weir by 1,500 gph for a medium flow -- about a 1/2-inch curtain. Use 1,000 gph for a lighter flow or 2,000 gph for a heavier flow. Look for a pump that will move the correct number of gallons at your waterfall's head height. For example, a 3-foot weir requires a 4,500-gph pump. If the pump is rated in gallons per minute, divide the gph by 60. A 4,500-gph pump is equivalent to a 75-gpm pump. If the waterfall is 5 feet high with 20 feet of tubing and three turns, get a pump rated for 4,500 gph at 8 feet of head.
How many gallons of water per hour for a waterfall?
To create a nice "average" looking waterfall or stream, it takes 1,800 gallons per hour (30 gallons per minute) for every 1 foot of width. To determine the GPH/GPM needed for your waterfall or stream - multiply the width in feet x 30 GPM.
How heavy is water in a pond?
To understand this you need to remember that water is heavy at 8 pounds per gallon - and the higher a pump has to push the water the less volume it will provide. Important - the feet of head is the distance from the surface of the water level in the pond to the top of the waterfall.
Application
Are looking to send water cascading over a waterfall or run a small fountain or send water through a UV clarifier?
Minimum Pump Size
Water needs to circulate through the filter at least once every 2 hours. This means that if you have a 1,000-gallon pond, you need a pump that can produce at least 500 gallons per hour or GPH. If you have fish, then it is best to double the pump's capacity to ensure that your water stays clean.
Measurements Needed
Head pressure and desired flow rate will influence the pump needed to power your water feature. Head pressure refers to the friction created when water is pumped uphill or over long distances. Flow rate will determine how much water moves through the feature. Below are some tips for calculating these measurements:
Types of Pumps
There are two classes of pumps, submersible and external. For ponds, submersible pumps are preferred because they can be hidden easily and used in skimmer boxes. There are several varieties of pumps available, so below is guide to help you determine which one is right for you.
What happens if you use too small tubing for pond pump?
Pond tubing is an often overlooked piece of pond equipment, but if you choose tubing that it too small, it will significantly decrease the flow of your pump. Pond owners often put a lot of thought into the pump they choose, but usually very little into which size tubing to use.
Why attach a small diameter tubing to a large pump?
Attaching a small diameter tubing to a large pump drastically increases the friction and restricts the flow. In addition, the longer the length of pipe used, the pronounced the effect is.
How much friction loss is in a Tsurumi 3PL pump?
Let’s say you purchased a Tsurumi 3PL pump. This pump has a maximum output of 3300 GPH. As mentioned in the example above, if you run 50’ of 1 ½” tubing to waterfall, there will be around 10’ of friction loss in the pipe (equivalent to 10’ of head pressure). From the chart below, at 10’ of head, the Model 3PL’s output will be reduced to 1800 GPH. But if you use 2” pipe, the friction loss is equivalent to 3′ of head and the pump output will be around 3100 GPH
Is 3000 GPH better than 3300 GPH?
Although the 3000 GPH in the chart is less than the 3300 GPH of your pump, there will be little reduction in flow if you are using only 10’of tubing. If you needed to use longer runs of tubing, like 50″ in the example above, it is definitely worth while to go to the next larger size of tubing (2″) to get the best performance from your pump.
Water Circulation Factors
Calculating Head and Lift Height
- Two of the most important measurements in sizing a pond or fountain pump are the maximum head height rating and maximum lift. Head height represents the vertical height the pump raises water above the surface of the pond. The top height the pond fountain pump can lift the water up from the pond surface is called “maximum head.” Any horizontal/diagonal flow is then measure…
Powering The Pump
- When selecting a pond pump, it’s important to keep in mind that pumps have different cord lengths. Make sure the cord is long enough to go through the pond and plug in far away from the water. Some electrical codes specify that the outlet for water features must be at least 6 feet away from the water. Make sure you are using an outlet designed for outdoor use, with a groun…
Selecting The Proper Pond Water Pump Tubing
- It is also important to use the correct tubing size because it has a direct effect on the pond pump’s maximum lift capability. If you use smaller tubing than specified you will limit the pump’s maximum lift and the amount of water circulated. Choosing the right pond water pump for your pond or fountain requires careful consideration and a little research upfront. Doing so will go a l…
